Subpanel install planning - placement

[Prometheus]

So it's January, and I'm starting to plan for my garage work this coming spring/summer. My house currently has 150 amp service, but the garage lights, outdoor outlets, and garage outlets are all currently on one 15 amp circuit. The main panel is also at the opposite end of the house. All signs point to a subpanel in the garage.

My struggle is where to put the panel and how to make it look somewhat aesthetically pleasing. This is a quick drawing of the floor layout:

The back wall (that isn't actually drawn in) is shared with the house and is insulated and sheetrocked per code. This is also the wall through which the cable supplying the power to the subpanel will come through. So, it also makes sense for this to be the wall the panel will be located on. The new outlets/light circuits will all run through the attic and then drop down the walls (ie I'm not doing surface mount conduit throughout). In my dream world, the panel would be flush mounted for a cleaner look, but I'm afraid it would compress the insulation too much. I could surface mount it and build a chase to make it look nicer, but I don't really love the idea of that either. It would wind up being a floor to ceiling chase somewhere on the wall. Are there any other alternatives I'm not thinking of? Thanks

I don't think the area that the flush panel would occupy would compromise your insulation envelope. There are some restrictions on panel placement, height, clear space to each side and in front. Be sure to find out about that. However, generally you cannot install anything that has a surface area of more than 16 sq in into a rated wall.

Others may clarify that or have more information. Someone here will come along with the proper information and perhaps cite the code for you.
